We divide 138125 by 20
We want to figure out the number of times 138125 can be divided by 20.

Step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 20

On to step 2:
The number 20 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 20

Let's proceed to step 3:
The number 20 fits into 138 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 120 from 138 leaves us with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 20

Going ahead to step 4:
20 goes into 181 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtract 180 from 181 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 20

Going ahead to step 5:
The number 20 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 690.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 20

Step 6:
125 divided by 20 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6906.0
Subtracting 120 from 125 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 20 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 6906.2
The remainder is 10 after subtracting 40 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6906.25
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6906.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6906.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 6906.25, and the remainder is 0.0.
